I,m not going to start another KDE4 + Nvidia = worse than using windows XP with 64 MB of RAM.

Im about to buy another computer and i'd like to know if is there any work in progress to make KDE work like it should have long ago, so I can stick with Nvidia.
Please i'd like to hear something from someone at Nvidia.

And please do NOT start commenting things like "You cant configure your computer" or "It works for me™" or "No body uses KDE" or "Disable compositing" and so on.

Kind regards.

Do what I did. Switch to ATI. There are some good deals for Radeon HD 5850 cards for around $260.

Other than that AaronP mentioned that Firefox may be slow cause it allocates larger pixmaps than the graphics card can handle. Maybe that's the same problem with KDE 4 cause KDE 3 isn't slow on Nvidia cards.
